在您的表视图单元格内使用容器视图,将标记分配为99。 使单元格高度略大于卡片(容器视图)。
并给您的卡片视图添加阴影效果。
UIView* shadowView = [cell viewWithTag:99];
shadowView.backgroundColor=[UIColor colorWithRed:228.0/255.0 green:228.0/255.0 blue:228.0/255.0 alpha:0.5];
[shadowView.layer setCornerRadius:5.0f];
[shadowView.layer setBorderColor:[UIColor lightGrayColor].CGColor];
[shadowView.layer setBorderWidth:0.2f];
[shadowView.layer setShadowColor:[UIColor colorWithRed:225.0/255.0 green:228.0/255.0 blue:228.0/255.0 alpha:1.0].CGColor];
[shadowView.layer setShadowOpacity:1.0];
[shadowView.layer setShadowRadius:5.0];
[shadowView.layer setShadowOffset:CGSizeMake(5.0f, 5.0f)];
关于Swift 3.0的临时解决方案:
extension UIView {
func setCardView(){
layer.cornerRadius = 5.0
layer.borderColor = UIColor.clear.cgColor
layer.borderWidth = 5.0
layer.shadowOpacity = 0.5
layer.shadowColor = UIColor.lightGray.cgColor
layer.shadowRadius = 5.0
layer.shadowOffset = CGSize(width:5, height: 5)
layer.masksToBounds = true
}
}
使用方法:
在 cellForRowAt indexPath 中使用:
var cell = UITableViewCell()
cell.contentView.setCardView()
func setCardView(view : UIView){
view.layer.masksToBounds = false
view.layer.shadowOffset = CGSizeMake(0, 0);
view.layer.cornerRadius = 1;
view.layer.shadowRadius = 1;
view.layer.shadowOpacity = 0.5;
}
UIView *viewTemp= (UIView *)view;
viewTemp.layer.shadowColor = [UIColor darkGrayColor].CGColor;
viewTemp.layer.shadowOffset = CGSizeMake(0, 2);
viewTemp.layer.shadowOpacity = 0.8;
viewTemp.layer.shadowRadius = 3;
viewTemp.layer.masksToBounds = NO;
extension UIView {
func addShadow(){
self.layer.cornerRadius = 20.0
self.layer.shadowColor = UIColor.gray.cgColor
self.layer.shadowOffset = CGSize(width: 0.0, height: 0.0)
self.layer.shadowRadius = 12.0
self.layer.shadowOpacity = 0.7
}
}
